Those are the basic operators but there are some far more useful ones on Twitter.

Attitude Search:

By adding a :), :( or ? you can search for positive or negative tweets on Twitter or those who are asking a question about something. These searches are very useful when looking for people’s views and reactions about an issue, product, movie or a service.

Time & Place:

Twitter has been absolutely vital in following citizen journalists and news coming from a specific location so naturally searching for tweets in a specific area is very handy. Also, now you can see what is trending in a specific area by clicking the trends drop down menu on the Twitter homepage.

Links & Sources:

There is only so much that you can say in a 140 characters, hence people like to share links of news, articles, opinions, services and practically anything else. Consequently, a good chunk of the value that comes from Twitter stems from the links it circulates. Therefore, to filter out only those tweets that contain link,s be sure to use the “filter:links” operator, while the “source:” operator will allow you to view tweets sent from a certain platform which might be limited in use.
